Application filed ctober 20, 1926. Serial No. 142,893.

The invention relates to machines for making paper receptacles and particularly for paper receptacles used in connection with toy torpedoes, in which an explosive charge is placed with gravel.

A further object is receptacle making machine wherein a strip of paper is fed into the machine by feeding mechanism, twisted around spindleshaving a planetary movement, and which spindles,

during their planetary movement,move adj acent mechanism which cooperates with the portion of the container extending beyond the spindles and folds and twists said por 'tion of the container for closing one end thereof. Also to provide in connection with the feeding mechanism, severing means which will sever the strip of paper.

A further object is to provide paper strip feeding mechanism, which will feed simultaneously to the spindles a narrower strip of paper which will be twisted around the spindles simultaneously with the wide strip in a position where it will be spaced from the sides of the wide strip, thereby forming a shell over the opposite edges of which the ends of the container may be folded inwardly for forming a substantially cylindrically shaped receptacle. Also to provide means 0 whereby the length of the strips, both narrow and wide, fed to the spindles may be varied.

A further object is to provide a large stationary gear, with which the spindle rotat- 1 ing pinions mesh during the rotation of a disc to which the spindle frames are pivotally connected,-and to proportion said gears whereby when the spindles are adjacent thedischarge end of the feeding mechanism, spring closed gripping jaws carried by the spindles will be in position for gripping the ends of the paper strips. Also to provide means cooperating with the spindle gripping jaws whereby when they assume positions adjacent the strip feedingmechanism,

said gripping jaws will be automatically opened, and allowed to closeupon the further movement of the spindles.

' A further object is to provide yieldable means with 'which the splndles engage in their planetary movement for holding the strips of paper as they are wrapped around to provide a paper.

the spindles. Also to provide an arcuately shaped tapered slot through which the portions ofthe containers extending beyond the ends of the spindles pass and are twisted to closed position.

A further object is to provide a finger extendlng into the restricted end closing slot for engaging the portion of the container beyond the spindles for folding one side thereof inwardly adjacent the seam or end of the outer strip, thereby locking the end of the strip by the following twisting operation. and means for moving said finger outwardly thereby preventing tearing of the projecting portion of the container during its further movement.

A further object is to provide the spindle carrying frames with arms having rollers disposed in a cam slot in a stationary disc, and said cam slot with a U-shaped portion adjacent the feeding mechanism, and into which the roller passes thereby pivotally moving the spindle and its frame to speed the same up in its movement with its gear in mesh with an inwardly movable segmentof the large gear, thereby allowing the spindle to have a slight pause at the point of gripping for taking care of the time incident to the gripping operation and feeding of the strips under the gripping jaw of each spindle.

A further object is to provide a pivotally mounted member having a yieldable projection and positioned whereby as the spindles pass from the twisting slot, pressure will be applied on the twisted ends of the container, thereby insuring a positive closing of the end of the receptacle.

A further object is to provide a cam slot into which rollers carried by. the spindle frames pass, and which rollers force forwardly the spindles thereby pulling the gripping jaws from the formed containers, and rods slidably mounted in said spindles and having lugs extending beyond the sides there'- of, and which rods engage cam means for holding said rods against rearward movement as the spindles are retracted by the engagement of the rollers in the cam slots, therebv causing said rods to force the formed containers from thespindles', into a hopper and before they again reachthe feeding mechanism, and spring means for returning said rods to normalinner position after their rear ends have passed out of engagement with the cam whichcooperates with .their rear ends.

A further object is to provide means whereby the narrow and wide strips of paper may be discharged in engagement with each other to the spindles, and frictional griparrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

Referring to the drawings, the numeral 1 designates the bed plate of the machine, which is preferably supported on legs 2. Extending upwardly from opposite sides of the bed plate 1 are brackets thin-bearings of Which the transversely disposed shaft 4 is rotatabl mounted. The shaft 4- at its outer end is provided with a worin gear 5, with which the worm 6 meshes, and which worm 6 is carried by a shaft 7, one end of which is provided with a hand wheel 8 adapted to be grasped by the operator for manual operation if desired, for instance for rotating the parts during repair or adjustment. Secured to the shaft 7 is drive pulley 9, over which a belt 10 extends, and which belt extends downwardly over the pulley 11 carried by the motor 12, which motor is pref- .sleeve 13. at its outer end is provided with a flange 14 which is anchored by means of bolts 15 to one of the brackets 3. The inner end of the sleeve 13 is secured by means of bolts 16 to a cam disc 17 having a cam slot- 18 therein, and which camdisc remains stationary during the operation of the machine, and secured to the cam disc 17- by means of bolts 19 is a large gear 20, which large gear remains stationary at all times. Disposed adjacent the cam disc 17 and secured to the shaft 4 and rotatable therewith is a spindle carrying disc 21, to which are pivotally connected at 22 the spaced arms 23 of the spindle frame 24, in which are rotatably mounted sleeves 25 having pinions 26, and which pinions mesh with the large gear 20. It will be seen that as the spindle carrying disc 21 is rotated in the direction of the arrow (1, Fig-' ure 1, with the pinions 26 in mesh with the large stationary gear 20, said pinions 26 will have a planetary action, and the sleeves 25 greater portion of their movement.

willv be rotated, and as said sleeves are slidably keyed at 27 to the spindle shafts 28, the spindles 29 will be simultaneously rotated for twisting the main and auxiliary tapered strips 30 and 30 around the spindles. 'One of the arms 23 of each spindle frame 24 is provided with angularly disposed arins 31 having rollers 32 thereon, and which rollers are disposed in the cam slots 18 of the cam disc 17 and maintain the spindle frames 24 radially disposed during the The paper strips 30 and 30 are fed to the spindles by feeding mechanism hereinafter set forth through the discharge end 33 of the paper feed chutes 34 and 35 which merge together, and as the spindles approach a horizontal position as shown in Figure 4, and at which time the gripping jaws 36 of the spindles are automatically opened for receiving the ends of the paper strips and gripping and frictionally holding the same. It is obvious that a slight delayed action is necessary for accomplishing the gripping operation, and to obtain this result the spindle frames, as the spindles approach the gripping position, are allowed to advance rapidly in relation to the speed of rotation of the disc 21, and to be then forced to radial position, which will give a slight delayed operation of the spindle frame for the gripping operation. To accomplish the above result, and referring particularly to Figure 7, a segment 37 of the large stationary gear 20 is pivotally mounted at 38, and the cam slot 18 is provided with an inwardly extending V-shaped portion 19, into which the rollers 32 carried by the arms 31 pass, as the frames approach the gripping position, therefore it will be seen that the V-shaped portion of the cam slot 18 will tilt the arms 31 of the spindle frames ,inwardly, thereby allowing the spindles 29 to advance in relation to the speed of rotation of the disc 21 as clearly shown in Figure 7. Referring to Figure 7, it will be seen that the gear segment 37 has been moved inwardly against the action of the spring for allowing the tilting operation of the frame, as the roller 32 passes through the portion 19 of the cam slot 18 it will be seen that the spindle frame 24 will be allowed to have a retarded action in moving to a radial position, and which action will be sufficiently retarded to allow for the gripping operation. The strips are cut from rolls as they are fed through the mechanism hereinafter set forth.

As the strips are cut from the paper fed into the machine, they are twisted around the spindles 29 with the narrow strip 30 inside thereof to form a reinforcing for the containers as clearly shown in Figure 19, and after which the ends are folded over the'ends of the reinforcing. As the strips are twisted ,It will be noted by referring to bracket or arcua-te plate 41, which is supported by the bracket arm 42. The spring arms 40 press on the strips wrapped around the spindles and prevent unwindin thereof. igure 15 that the strip 30 is narrower than the strip 30, and that one side of the strip 30 extends beyond the outer end of the spindle 29, therefore it will be seen that the portion 30 of the container, which extends beyond the outer end of the spindle 29 is to be folded inwardly for closing one end of the container as shown in Figure 21. However to get the best results and a locked seam a finger 43 is provided, which finger is carried by a transversely-movable rod 44, which is normally forced in one direction by means of a coiled spring 45, and which finger is adapted to be moved inwardly into the cam slot 46 immediately before the container end enters said slot for crimping the end 30 inwardly at 30, Figure 20, adjacent the end fold of the outer strip of paper 30, and then to immediately move outwardly so it will not tear the adjacent portion 30 of the container end, and which portion 30 mo-ves through the restr cted slot 46 whereby it gets a twisting action which folds in the end of the container. To move the rod 44 longitudinally said rod is provided with a cam plate 47 which is in the path of the rollers 48 carried by the spindle frames 24, and .it will be seen that as said rollers engage the cam plate 47, the rod 44 will be immediately moved in one direction, which will force the finger 43 into the cam slot 46, and as said rollers pass out of engagement with the plate 47 spring.

45 will move the rod 44 in the opposite direction, thereby withdrawing the finger 43 from the cam slot 46. The cam slot member 49 is supported by brackets 50, which are secured to one of the brackets 3. As the spindles continue in their rotation in the direction of the arrow a, Figure 1, with their portions 30 in the cam slot 46 which is restricted to a vanishing portion, said portions 30 will be twisted for closing the end of the container, however to more positively apply pressure to the ends of the container a pivoted presser member 51 is provided on the bed plate 1, and which is pivotally connected at 52 to a bracket 53, and which member is normally forced to an upwardly and inclined position by means of a spring 54 to a position where the stop 55 carried there by will be in the path of the ends of the spindles so that said spindles will force the pressed member 51 downwardly with its spring actuated plunger 56 in engagement with the end of the container, thereby allowing said spring actuated plunger 56 to apply pressure to the closed ends of the receptacle. .Plunger 56 is preferably bevelled at 57 to allow the spindles to easily cam past the same into engagement with the member and to slide off said spring actuated plunger during the continuous rotation of the spindle in its planetary movement.

The rollers 48 engage the rear side of the gulde' ring 58 during the operation of the device as clearly shown in Figure 2, however it is obvious that when the spindles have passed through the operations for closing the end of the receptacle it will be necessary to remove said receptacles from the spindles, and this removing operation can be easily facilitated by loosening the receptacles on the spindles, and to accomplish the above result the next operation is broadly to force the spindles 19 outwardly without outward movement of the gripping jaws 36, thereby releasing the binding action of the jaws 36 within the container, and then to force the loosened container fro-m the spindle. The gripping jaws 36 have suflicient tension to hold the ends of the strips during the twisting operation, but not suflicientiension or frictional holding power to prevent the formed receptacles to be forced outwardly from the spindles. To accomplish the above result the rollers 48 pass through the cam slot 59 at the lower side'of the ring 58, and as said rollers are carried by bars 60 slidably mounted in thespindle frames 24,

and which bars areconnected by yokes 61 to the spindle shank 28, said spindle shanks and the spindles 29 will be moved in the direction of the arrow 6, Figure 6, as they are slidably keyed at 27. At the same time the container removing rod 62 moves forwardly with the spindles 29, however the gripping jaw 36, which'is carried by the sleeve 25 remains stationary with the exception that it rotates, therefore it will be seen that the gripping jaw 36 will be pulled from the container during the outer axial movement of the container, as the rollers 48 pass through the cam slot 59, the spindle 29 will be pulled inwardly, however the container removing rod 62 will be held against inward movement by the engagement of the rear end thereof with the arcuate plate 63, consequently its lugs 64, which extend outwardly from the opposite side of the spindle slot 65 will engage the inner end of the receptacle and will force the receptacle from the spindle, thereby allowing the receptacle to drop into the hopper 66 and to be discharged therefrom into a suitable receptacle 67. The gripping jaws 36 have only sufficient gripping action to hold the containers against outward axial movement under nor mal conditions, but not suflicient gripping action to prevent the outward removal of the receptacle upon outward movement of the spindles 29, during the jaw removing operation, After the inner end of the rods 62 pass out of engagement with the arcuate plate 53, the coiled springs 68 which surround said rods and are interposed between the washers 69 and the spindle shanks 28, force said rods 62 inwardly to their normal positions and the spindles are again in osition to grip strips at the point of fee ing. Gripping jaws 36 are pivotally mounted at 70 on sleeves 71, which are clamped on the sleeves 25 and are normally held in closed positions by means of coiled springs 72.

Referring to Figures 4 and 5 wherein the feeding mechanism is particularly shown, said feeding mechanism is supported by a bracket 73 and the strips 30 and 30 are fed towards the spindles 29 when in gripped position through the guide chutes 34 and 35.

mally forced rearwardly by means of the coiled spring 77 connected thereto and anchored at 78 to the fixed arm 79. Arm 76 is provided with a right angularly disposed arm 80 disposed in the path of the'pi'voted trip lever 81, which is pivotally connected at 82 to the bracket 83 and has its angularly disposed arm 84 pivoted whereby when said trip lever 81 is forced towards the spindles 29 by the engagement of the member 85 carried by said lever with the rotatable cam 86, which rotates in the direction of the arrow 1), Figure 5, the arm 84 will be in the path of the gripping jaw arm 87 of the adjacent spindle, thereby raising the gripping jaw at the time of feeding of the ends of the strips 30 and 38 to the spindle. The continued rotation of the cam 86 is timed whereby the gripping jaw is released and the retarded operation of the spindle frames above referred to is to allow the positive gripping. As the arm 81 moves forwardly it engages the arm 80 and raises the gripping member 75, thereby allowingthe strips 30 and 30 to be twisted around the spindle. However to positively feed the strips 30 and 30 a plurality of feed rollers 87 and 88 are provided, which rollers extend into opposite sides of the chutes 34 and 35 and grip the strips of paper, that is when the feed rollers 87 are rotated to positions where their corners 89 will engage the strips of paper and force said spindles reach and, pass the gripping position. It is obvious that the length of the paper strip fed to the device may be varied by varying the position of the rollers 87 and 88 on their drive shafts 90 for varying the position of the shoulders 89 of the gripping rollers. The mechanism shown in Figure 5 is in the cutting position, that is, the pivoted cutters 91 and 92 are in closed position and have severed the strips 30 and 30*, and it will be noted that the severed portion of the strip 30 is shorter than the severed portion of the strip 30, which will leave the extension of the strip 30 extending beyond one end of the strip 30 and which extension, after the container is formed on'the spindle will make a turn around the container for entirely concealing the reinforcing strip therein.' The friction rollers 88 are carried by shafts 93 which extend through bearings of the brackets 73 and the shafts 90 also extend through bearings of said brackets 78 and have their outer ends geared together by a gear train driven by one of the shafts 90, and which shaft is provided with'a gear 94 which is rotated by a worm 95, said last named' shaft 90 has mounted'thereon a gear 96 which meshes with a gear 97, and which gear meshes with a gear 98 which in turn drives the gear 99, Which meshes with the gear .100. Gear 98 also drives the gear 101, and the gear 97 drives the pinion 102, and the gear 103 throughthe intermediate gear 104.

The gear 97 is relatively wide and also drives the idle gear 105, which in turn drives the gear 106 which meshes with the small gear 107, therefore it will be seen that all of the feed and friction rollers of the feeding mechanism will be simultaneously rotated in the direction of the various arrows shown in Fig. 5. The worm 95 is carried by a shaft 108, which shaft is provided with a slidable clutch member 109 which cooperates with a conventional form of cone clutch 110 carried by the pulley 9 and shaft 7, and the coiled spring 111 normally maintains said clutch elements in clutched relation whereby during the operation of the motor 12 the spindle and feeding mechanism are simultaneously operated. The clutch element 109 has connected thereto a lever 112 which lever When moved in the dlIGCtlOll of the arrow 0, Figure 1, will stop the feeding mechanism and a spring arm 113 is preferably provided for cooperating with one side of the lever 112 and holding the same in open position.

The pivoted cutter blades 91 and 92, which are shown in Figure 5 in closed position where they have severed the strips 30 and 30 for allowing the severed ends of the strips to be pulled onto the spindle are operated from adjacent shafts 90, and which shafts are provided with cams 114 and 115 which rotate in the direction of rotation of the feed rollers 87 carried by the shafts 90,

[and in their rotation engage the cam noses 116 of the arms 117 and 118 of the bell crank levers 119 and 120, arms of which overlie thebuter ends of the pivoted cutter blades 91 and 92 and force the same to closed position thereby severing the strips -30 and 30 transversely and in proper lengths for forming the receptacles. As soon as the cam members 114 and 115 pass the cam noses 116 which will release pressure on the cutter blades 91 and 92, the springs 121 and 122 will immediately move said cutter blades to open positions. After the cutting operation the cam 86 will force the lever 87 towards the spindle 29 for opening said spindle and will simultaneously raise the presser member 75 thereby releasing the severed ends of the strips and allowing the same to be pulled from the chutes by the rotation of the spindles. At the same time additional paper is fed inwardly by the other rollers 87 and 88. To prevent the strips 30 and 30 from coming out of the chutes after a severing operation plates 123 are provided which rest upon the strips and exert sufficient frictional power thereon to prevent rearward slipping of the paper. The strips of paper 30 are preferably carried in rolls 124, which are mounted on a roll rack 125, however it is to be understood that this mechanism may be varied as desired.

From the above it will be seen that a container making machine is provided wherein strips of paper are fed into the machine by a feeding mechanism, wrapped around spindles as they reach the feeding position, conveyed from the feeding position b the spindles, crimped inwardly on one si e adjacent the end of the last wrapping, thereby forming a locked joint, the projecting ends so crimped twisted, additional pressure applied on thetwisted end of the receptacle, the gripping jaws withdrawn from the receptacle and means provided for forcing the receptacle so formed from the spindle. It will also be seen that the containers can be used for various purposes, however they are particularly adapted for use in making toy torpedoes, and it will be noted the machine closes one end only of the container, and where used in connection with torpedoes, the explosive charge and gravel are placed in the open end of the receptacle and the portion extending beyond the reinforcing machine is folded inwardly for closing the torpedo, said last named folding is usually a manual one.

The knife .91 is maintainednormally open by means of the spring 126 and the lever 81 i1n7inoperative position by'the coiled spring Referring to Figures 21 and 22 wherein a modified form of spindle is shown, the spindle is provided with a paper guide 128 which is in disc form and held on the spindle by means of a set screw 129. It will be noted that the disc is provided with a recess 130 extending inwardly from one side thereof, which disc will allow free move-' ment of the gripping jaw 36 in its movement to open or closed position, and such a guide may be used if desired.
